Claims

[Claims for Utility Model Registration] A plurality of flat hollow bodies for fluid circulation arranged in parallel so that both ends are open and their lengths face upward and downward, and fins arranged between adjacent hollow bodies. and a cross section approximately U.
The header body is shaped like a letter and is joined to both the upper and lower ends of the heat exchanger part so that the opening faces the heat exchanger part, and the header has a closing member welded to both ends of the header body and to the heat exchanger part. In the exchanger, the left and right sides of the heat exchange part protrude laterally than the left and right ends of the header, and the closing member is approximately square or semicircular when viewed from the front, and is welded to both ends of the header body. The space between the upper and lower ends of the protruding part of the heat exchanger and the left and right ends of the upper and lower header bodies is Heat exchanger covered with a closure member.
